To determine if 212 is a prime number or a composite number, we simply look at the factors for 212.
If the factors of 212 are only 212 and 1, then we know that 212 is a prime number. Otherwise, 212 is a composite number.
To explain better, if 212 is only divisible by 1 and 212, then it is a prime number, and if 212 is divisible by more than 212 and 1, then it is a composite number.
The factors of 212 are as follows:
1, 2, 4, 53, 106, 212
Therefore, since 212 is divisible by more than one and itself, the answer to the
question "Is 212 prime or composite?" is highlighted in blue below.
composite
Is 213 prime or composite?
OK. Now you know that 212 is a composite number. Use our logic above and see if
you can figure out if the next number on our list is prime or composite before you check your answer.
